I love thrillers that involves a doctor running experiments that leads up to no good. Where the main character has to fight for their lives before the doctor has a chance to get rid of them. It is like an edge of your seat sort of read that makes you want to read until you get to the end. It leaves you wanting more. Will the main character get away or will she fall into to the doctor's experiments. Will the experiment cause the main character to doubt their sanity and come to want to let the doctor get away with what he is doing? Will the main character get a chance to fight back and kill the doctor? Are will the main character come to believe in what doctor is doing and will help him get another person to add to his evil experiments?
